One of our sister sites, Gas2.org, recently had a great infographic on the energy efficiency of movement that I thought was worth a share on here as well. As I point out repeatedly here on Planetsave, transportation is one of the biggest contributors to our environmental problems and one of the critical factors in our modern world that reduces our quality of life. The infographic mentions, for instance, that 22% of worldwide energy use and 27% of carbon emissions are from transportation (the figures are even higher in the U.S.).

Ever wonder how much energy is used by your different major appliances or electronics? Or how much energy all such appliances and electronics in the U.S. use? Here’s some info on that for four big ones: TVs, computers, clothes dryers, and refrigerators.
Before checking it out, try to guess how much each of these use in an hour — see how close you come!
I covered the rebound effect here on Planetsave a couple times a couple months ago. The common argument of rebound effect enthusiasts is that energy efficiency actually increases energy use. Sound hard to believe? Yeah, that’s because it’s not true. Anyway, NRDC’s David Goldstein, Sierra Martinez, and Robin Roy delved into this topic in more depth recently and I’m reposting a great article by David Goldstein on their new report below.
Following up on my post about the rebound effect & Jevons paradox, someone commenting on that post added a lot of useful information/ideas.
A new study published in the January issue of the journal BioScience has found a strong correlation between global energy use and economic growth. The research has led the authors to infer that energy use limits economic activity directly, and that an “enormous” increase in energy supply will be necessary to meet the demands of […]
Our most recent Going Green Tips post was on “cutting the coal.” One of the best ways to cut the coal is to cut back on your electricity usage, and one of the best ways to do that, especially if you live in the South, is to cut the air conditioning. Author Chip Haynes, who […]
This guest post is another great response to the recent oil fire in the Gulf of Mexico, the horrible BP oil spill, the Massey Energy coal mining disaster earlier this year, and potential dirty energy disasters we may see in the future if we don’t take action now. The author, Brian F. Keane, is president […]
